In the rapidly evolving field of wireless communication technology, performance requirements for communication modules have become increasingly demanding. The RF9209 2.4GHz wireless transceiver module is designed based on the EM9209 wireless chip from EM Microelectronic – Marin SA, a leading RF company under the Swiss SWATCH GROUP. In addition to its low cost, compact size, and stable performance, the module features a maximum transmit power of 10dBm, a receive current of just 7mA, and a high receive sensitivity of -115dBm. Tests have shown that it can achieve a transmission range of up to 500 meters. The module meets FCC and ETSI specification requirements, making it suitable for certification needs.

Low Power Consumption: Energy-Efficient Design for Extended Battery Life

Low Receive Current
Thanks to the Swatch Group’s EM9209 chip, the RF9209 module demonstrates excellent low-power performance during data reception, with a receive current of just 7mA. Compared to similar modules that typically consume 10mA or more, this represents over a 30% reduction in power consumption, significantly extending device battery life.

Efficient Transmission with Remarkable Power Savings
When transmitting data at a power output of +10dBm, the RF9209 module operates with a transmit current of only 36mA. In contrast, other modules delivering similar output may draw 50mA or even more. The EM9209 chip from Swatch Group enables optimized performance that reduces power consumption without compromising transmission capability.

Ultra-Low Shutdown Consumption for Long Standby Life
The RF9209 module supports an ultra-low power shutdown mode, consuming less than 10nA—virtually zero. This makes it ideal for applications such as smart locks or environmental monitoring sensors that require long standby periods, significantly prolonging standby time.

High Sensitivity: Ensuring Stable Communication

With the Swatch Group’s EM9209 chip at its core, the RF9209 module achieves a high receive sensitivity of -115dBm @1.5K, allowing it to accurately capture weak signals. This makes it especially effective in complex environments with poor signal conditions—such as urban canyons or remote areas—ensuring stable and reliable wireless communication.

Frequency Hopping for Anti-Interference and Smoother Data Transmission
The RF9209 module supports frequency hopping, which helps it avoid interference by dynamically switching frequencies. This feature is particularly useful in electromagnetically noisy environments like industrial control sites or smart home systems, where it ensures smooth and uninterrupted data transmission.
